What is the main function of a cpu?
The main functions are: interpreting computer instructions and processing data in computer software.
The CPU is the core component of a computer that is responsible for reading instructions, decoding them and executing them. The CPU consists of two main parts, namely, the controller, the operator, which also includes cache memory and the realization of the link between them, the data, control of the bus.
The three core components of a computer are the CPU, internal memory, and input/output devices. The efficacy of the central processor is mainly for processing instructions, performing operations, controlling time, and processing data.
In the computer architecture, the CPU is all the hardware resources of the computer (such as memory, input/output units) to control the deployment, the core hardware unit to perform general-purpose operations. the CPU is the core of the computer’s computing and control. The CPU is the core of computing and control of the computer. All the operations in the software layer of the computer system will eventually be mapped to CPU operations through the instruction set.
CPU appeared in the era of large-scale integrated circuits, processor architectural design iteration update and integrated circuit process to promote its continuous development and improvement. From the initial dedicated to mathematical computing to widely used in general-purpose computing, from 4-bit to 8-bit, 16-bit, 32-bit processors, and finally to 64-bit processors, from the manufacturers are not compatible with each other to the emergence of different instruction set architectural specifications, the CPU has been in rapid development since its inception.
The role of the cpu
1, the main role of the CPU: processing instructions, perform operations, request for action, control time, processing data.
2, the central processing unit (CPU, centralprocessingunit) as the core of the computer system computing and control, is the information processing, program operation of the final execution unit. CPU since its creation, in the logical structure, operational efficiency, and the functionality of the extension of the great development.
3, the central processing unit (CPU), is one of the main equipment of the computer, the core of the computer accessories. Its function is mainly to interpret the computer instructions and process the data in the computer software.CPU is the core component of the computer responsible for reading instructions, decoding instructions and executing instructions. The central processing unit consists of two main parts, namely, the controller, the operator, which also includes cache memory and the realization of the link between them, the data, control of the bus.
